Accola put her engagement ring on display in the picture, and in a subsequent photo she posted of her and King laughing together. Nina Dobrev was quick to congratulate her co-star. "DYING RIGHT NOW! SO excited/thrilled/happy/hyperventilating over ur engagement! #matchmadeinheaven I mean.. #matchmadebynina," Dobrev wrote. "What colors are we thinking for the bridesmaids dresses? Because yellow isn't a good color on me."

Post-proposal, King tweeted that he was a lucky man — and seemed to indicate that he proposed in front of a display of artisan cheeses. King, 33, and Accola met last year on the set of The Vampire Diaries.

Accola previously dated her co-star Zach Roerig. King, who recently released his debut solo EP Breaking, has two daughters from a previous relationship.
